From Wikipedia, the free encyclopedia

A hose is a hollow tube designed to carry fluids from one location to
another. Hoses are also sometimes called pipes (the
word pipe usually refers to a rigid tube, whereas a hose
is usually a flexible one), or more generally tubing. The shape of a hose is
usually cylindrical (having a circularcross section).

Hose design is based on a combination of application and
performance. Common factors are Size, Pressure Rating, Weight,
Length, Straight hose or Coilhose and Chemical Compatabiltiy.

Hoses are made from one or a combination of many different
materials. Applications mostly use nylon, polyurethane, polyethylene, PVC, or synthetic or natural rubbers,
based on the environment and pressure rating needed. In recent
years, hoses can also be manufactured from special grades of
polyethylene (LDPE and especially LLDPE). Other hose
materials include PTFE (Teflon), stainless steel and other metals.

To achieve a better pressure resistance hoses can be reinforced
with fibers or steel cord. Commonly used reinforcement methods are
braiding, spiralling, knitting and wrapping of fabric plies. The
reinfocement increases the pressure resistance but also the
stiffness. To obtain flexibility corrugations or bellows are used.
Usually circumferantial or helical reinforcement rings are applied
to maintain these corrugated or bellowed structures under internal
pressure.

Applications

Hoses can be used in water or
other liquid environments or
to convey air or
other gases. Hoses are used to carry
fluids through air or fluid environments, and they are typically
used with clamps,
spigots, flanges, and nozzles to control fluid flow.

Air hoses are used in
underwater diving (e.g., scuba diving) to
carry air from the surface or from air tanks. (See also Snorkeling.) Industrial uses for operating
flexible machinery and worktable tooling such as pneumatic screw
drivers, grinders, staplers, etc.

In building services, metal
or plastic hoses are used to
move water around a building; whilst air ducts are used to move
air around (see air conditioning). They can also be
used to take out vibration, and thermal or settlement
movement.

Automotive hoses are used in automobiles to move fluids around for use in
cooling, lubrication,
and/or hydraulics. Hoses are also used to
convey pressure or vacuum signals to control circuits or gauges, as
well as conveying vacuum to heating, cooling, brake, and/or locking
systems.

In chemistry and medicine, hoses (usually
called tubes) are used to move liquid chemicals or gases
around.

HOSE (aka H.O.S.E or S.H.O.E.) is a term used for playing a mixed game of poker consisting of four different poker games. H stands for Hold'em, O for Omaha Eight or Better, S for 7 Card Stud and E for 7 Card Stud Eight or Better. This form of poker is most common at higher limit casino tables and is popular since it requires players to be skilled at many different forms of poker to succeed.

From LoveToKnow 1911

HOSE (a word common to many Teutonic languages; cf.
Dutch, hoos,stocking, Ger. Hose, breeches,
tights; the ultimate origin is unknown), the name of an article of
dress, used as a covering for
the leg and foot. The word has been
used for various forms of a long stocking covering both the foot
and leg (see Hosiery), and
this is the usual modern sense. But it also formerly meant a kind
of gaiter covering the leg from the knee to the ankle only, of the long tight covering for the
whole of the lower limbs, and later of the short puffed or slashed
breeches worn with the doublet - at this period, from the early part
of the 16th century onwards, comes the distinction between the
"hose" or "trunk hose" and the
stocking (see Costume). The
term is applied to certain objects resembling such a covering, as
in its application to flexible rubber or canvas piping used for conveying water (see
Hosepipe), and in botany, to
the "sheath" covering, e.g. the ear of corn. The
term "hose-inhose" is thus used in botany for a flower in which the corolla has become doubled,
as though a second were inserted in the throat of the first; it occurs sometimes in the
primrose.
